GraphNode Class

Get the list of all links (incoming and outgoing).

Return all categories. Never returns null.

Return number of categories in the object.

Creates a delimited list of all category labels for this graph object.

Get the document local schema from the Owner of this graph.

Return true if this node is contained in one or more GraphGroups.

Unique identifier for the node

Returns the count of incoming links

Enumerable of incoming links. The order of the enumeration is random.

Returns true if the node is contained by any other node.

Returns true if the node is a container of any other node.

Get whether this object is is a group. It looks for the GraphCommonSchema.Group property on the object.

Get whether this object is Pseudo. It looks for the GraphProperties.IsPseudo

Property that gets or sets a property value.

Displayable label for the node. If no label is defined, this returns the Id so we always have something to display to the user.

Returns the count of outgoing and incoming links

Returns the count of outgoing links

Enumerable of outgoing links. The order of the enumeration is random.

Get the Graph object that this object belongs to.

Return all the GraphGroups that have this node listed in their ChildNodes collection (or ChildGroups collection if this node has IsGroup=true).

Property that returns an enumeration of all annotations. The order of the enumeration is random.

Property that returns an number of of all annotations.

Property that returns an enumeration of all annotation keys. The order of the enumeration is random.

Property that returns an enumeration of all annotation values. The order of the enumeration is random.

Helper property to get/set visibility property of a GraphObject

Add a category to the object

Converts the GraphObject to a GraphNode. If this is a GraphGroup, the inner node is returned. For types other than GraphNode/Group, null is returned.

Remove all categories from this object.

Removes the value of the specified property

Clear the value of the specified property.

Clones a Node, including all properties, and clones new Links from the original Node's Links

Clones a Node, including all properties, and clones new Links from the original Node's Links

Copy any new categories from the given object, keeping existing categories.

Copy any new properties from the given object, keeping existing property values unchanged.

Returns the list of all ancestor groups that contain this node. This is different from FindAncestors in that it only returns nodes that have IsGroup=true.

Walks recursively up all ancestors of this node and returns the unique set.

Walk down the containment links of this node and all it's descendants and return the unique set.

Finds the first node that matches the acceptNode predicate that is also related to this node according to the traverseLink and traverseNode predicates.
It is found by doing a breadth first search along links matching the traverseLink predicate, in the To or From direction designated by the searchDirection parameter. Returns null if it doesn't exist.

Get related nodes that have a containment relationship to this node

Get related nodes that have a containment relationship to this node

Finds the dgml nodes that matches the acceptNode predicate and are related in a way that matches the traverseLink and traverseNode predicates.
They are found by doing a breadth first search along links matching the traverseLink predicate, in the Source or Target direction designated by the searchDirection parameter. Then if the node matches the traverseNode predicate it keeps searching recurrsively through that node in the same direction and returns all nodes that match the acceptNode predicate. The search can handle circularity in the graph.

Return first matching leaf category that has the given category in its heirarchy.

Return first matching leaf category that has the given category in its heirarchy.

Gets the schema specific value of the property if one exists.

Gets the sources linked with this node via a link that matches at least 1 of the specified link categories.

Gets the targets linked with this node via a link that matches at least 1 of the specified link categories.

Gets the value of the specified annotation.

Gets the value of the specified property.

Gets the value of the specified property.

Gets the value of the specified property.

Gets the value of the specified property, and also return the category that this property value was inherited from if any.

Gets the value of the specified annotation. if property is not set we reutnr the default value that the caller pass to this method

Gets the value of the specified property.

Returns the given property as a string using the given culture.

Return true if the object has the given category.

Return true if the object has any of the given categories.

Return true if the object has the given category.

Determines if the given set of categories applies to this object.

Return true if the specified property exists on this object with no cateogry inheritance check.

For internal book keeping only.

Return true if the specified annotation exists.

Find out if the object has a value for the specified property.

True if the group is an ancestor of this node.

Raise a PropertyChangd event for the given GraphProperty

Override that notifies the GraphGroupCollection whenever the IsGroup property has changed on this node. This has to be synchronous so that GraphGroup is immediately available after this operation in the same transaction.

Remove this node from the graph

Remove the category of this object

Add an annotation using the given key, type and value

Sets the value of the given property. If the proeprty already exists, its value is overwritten unless the annotation flags prevent otherwise.

A more human friendly default string representation of a Node object

Modifies the current graph object to share the same property and categories as the given graph object. The wrapper and wrappee graph objects will always have identical sets of properties and categories.

Returns the label of an object or the id if the label is null. Should be used for tracing Microsoft.VisualStudio.Diagnostics.PerformanceProvider.DebugTrace.IDebugTracer
